| Off-Road Large Spark-Ignition (Gasoline and LPG) Equipment
Activities |
| This area of the Off-Road Mobile Sources website pertains to
off-road large spark-ignition (LSI) equipment greater than 25
horsepower, including farm, construction, and industrial equipment,
powered by gasoline and liquefied petroleum gas (LPG), and other
alternate fuels. Typical applications that use LSI engines include
forklifts, specialty vehicles, airport service vehicles, large turf
care equipment, portable generators, and a wide array of other
agricultural, construction, and general industrial equipment. The U.S.
EPA has sole authority to control new farm and construction equipment
under 175 horsepower. To find out more about the regulatory activities
and related information, please see the links below. |

On
April 21, 2008, ARB will host a public workshop to discuss proposed
amendments to the California regulations and test procedure for small
off-road engines (SORE) and large spark-ignition engines with an engine
displacement less than or equal to one liter (LSI ≤
1 L). Specifically,
the discussion will focus on standards for LSI ≤
1 L, modifications to
the SORE emissions credit program, and other minor changes to the
regulatory language. This is the second workshop in continuation
of the rulemaking process. The proposed regulations are scheduled
to be presented to the Board at the November 20-21, 2008
hearing. (Note: Board

At its May 25, 2006, board meeting,
the Air Resources Board voted to adopt the rules for new emission
standards, fleet requirements, and test procedures for forklifts and
other industrial equipment.
News Release

|
| Posted May 31, 2006: |
|
We have posted an additional interim
letter of verification in accordance with Mail Out #MSC 05-14 dated
April 11, 2005.
Interim Letter
In an effort to support introduction
of equipment for regulatory compliance or incentive programs in
California, ARB staff is using the Interim Verification Procedure to
evaluate LSI emission control systems. New information will be posted
as additional systems are given interim verifications. Please check
periodically for updates.
The proposed procedure will remain as part of LSI regulatory standards
to be developed and considered for approval by the Board in 2006. A
permanent Executive Order will replace this letter when ARB staff
finalizes a proposal for LSI engines before the Board. |

Air
Resources Board (ARB) consideration of the LSI rulemaking proposal has
been postponed and will be rescheduled to a later date. The month has
not been determined at this time, but consideration could be as early
as the May 25-26, 2006 Board hearing in Sacramento.
The ARB will post a "Notice of Recalendaring of Rulemaking Action for
the Hearing to Consider Adoption of New Emission Standards, Fleet
Requirements and Test Procedures for Forklifts and Other Industrial
Equipment" to the LSI Regulatory Activities web page once the item has been formally
rescheduled. Contents of that notice will be provided to the LSI list
serve at that time.
The record remains open and all comments regarding the proposal are
welcome. |
